Issue 876224 has been merged into this issue.

When comparing a passing shard #1 vs a timeout on shard #1

The pass looks like:

[1/254] WebViewFocusInteractiveTest.Focus_FocusTakeFocus (TIMED OUT)


With 75 tests timing out, and only completing 179/254 tests on the shard.

Nevermind, similar stack traces are showing up in other tests.

It looks like the bot can't tear down its renderer process correctly.

any progress on this?
